System and method for realizing streaming media content service

The invention discloses a system and a method for realizing streaming media content services. The invention combines P2P technique with CDN technique, connects a plurality of physical network administrative domains through communication networks and adopts constructing P2P network topology on EMSs in the domains. A DTS is also arranged in the domain, stores all storage content information of the EMSs in the domain and can fast find out the EMS storing certain media content when the searching delay of a DHT is larger. Besides, the DTS stores the information of cross-domain media content, and can fast locate the request to other domains when the media content requested by a user can not be found out in the domain. On one hand, the adoption of the invention resolves the poor expandability problem of the CDN system media capacity and user scale and reduces the effects of the bandwidth and the single point failure of a center node on other nodes in the system; and on the other hand, the arrangement of concentrative catalog servers guarantees the search time of nodes and ensures service quality.
